The Wealth of Nations_ Books 4-5 - Adam Smith [116]
In the exportation of their own surplus produce too, it is only with regard to certain commodities that the colonies of Great Britain are confined to the market of the mother country. These commodities having been enumerated in the act of navigation and in some other subsequent acts, have upon that account been called enumerated commodities. The rest are called non-enumerated; and may be exported directly to other countries provided it is in British or Plantation ships, of which the owners and three-fourths of the mariners are British subjects.
Among the non-enumerated commodities are some of the most important productions of America and the West Indies; grain of all sorts, lumber, salt provisions, fish, sugar, and rum.
Grain is naturally the first and principal object of the culture of all new colonies. By allowing them a very extensive market for it, the law encourages them to extend this culture much beyond the consumption of a thinly inhabited country, and thus to provide beforehand an ample subsistence for a continually increasing population.
In a country quite covered with wood, where timber consequently is of little or no value, the expense of clearing the ground is the principal obstacle to improvement. By allowing the colonies a very extensive market for their lumber, the law endeavours to facilitate improvement by raising the price of a commodity which would otherwise be of little value, and thereby enabling them to make some profit of what would otherwise be mere expense.
In a country neither half-peopled nor half-cultivated, cattle naturally multiply beyond the consumption of the inhabitants, and are often upon that account of little or no value. But it is necessary, it has already been shown, that the price of cattle should bear a certain proportion to that of corn before the greater part of the lands of any country can be improved. By allowing to American cattle, in all shapes, dead and alive, a very extensive market, the law endeavours to raise the value of a commodity of which the high price is so very essential to improvement. The good effects of this liberty, however, must be somewhat diminished by the 4th of George III. c. 15, which puts hides and skins among the enumerated commodities, and thereby tends to reduce the value of American cattle.
To increase the shipping and naval power of Great Britain, by the extenison of the fisheries of our colonies, is an object which the legislature seems to have had almost constantly in view. Those fisheries, upon this account, have had all the encouragement which freedom can give them, and they have flourished accordingly. The New England fishery in particular was, before the late disturbances, one of the most important, perhaps, in the world. The whale-fishery which, notwithstanding an extravagant bounty, is in Great Britain carried on to so little purpose that in the opinion of many people (which I do not, however, pretend to warrant) the whole produce does not much exceed the value of the bounties which are annually paid for it, is in New England carried on without any bounty to a very great extent. Fish is one of the principal articles with which the North Americans trade to Spain, Portugal, and the Mediterranean.
Sugar was originally an enumerated commodity which could be exported only to Great Britain. But in 1731, upon a representation of the sugar-planters, its exportation
